New Details About The Threatening Messages Nikolas Cruz Sent His Ex-Girlfriend ​— And Other Violent Warning Signs The Florida School Shooter's Classmates Witnessed

Cruz harassed her to the point where her family wasn't comfortable letting her go anywhere alone.

The Parkland shooter was expelled for fighting and had an abusive relationship with his ex-girlfriend.

Nikolas Cruz admitted to committing the third largest mass shooting in America on Feb. 14 and is charged with 17 counts of premeditated murder. Students who knew him said they weren’t surprised he shot up Marjory Stoneman Douglas High School because of his prior “erratic” behavior.

“The reason he got expelled was because he was fighting with his ex-girlfriend’s new boyfriend,” Connor Dietrich, 17, a junior at Florida’s Marjory Stoneman Douglas High School, told The New York Post.

“He stalked her and threatened her. He was like, ‘I’m going to kill you,’ and he would say awful things to her and harass her to the point I would walk her to the bus just to make sure she was OK. We all made sure she was never alone.”

“We were told last year that he wasn’t allowed on campus with a backpack on him,” said math teacher Jim Gard. “There were problems with him last year threatening students, and I guess he was asked to leave campus.”

Classmates of the suspected shooter were aware of his “troubled” behavior and claim to have reported him several times to school officials.

“He used to have weird, random outbursts, cursing at teachers,” Drew Fairchild, a Stoneman Douglas High student who previously shared a class with Cruz, told The Miami Herald. “He was a troubled kid.”

Multiple students confirmed to BuzzFeed that Cruz had indeed threatened his ex-girlfriend and the boy she was seeing.

Enea Sabadini, 17, the boy Cruz’s former girlfriend began dating, remembered Cruz posting threatening messages on his Instagram in 2017.

Sabadini said Cruz charged him in the school courtyard. Sabadini fought back and began punching Cruz in the face.

"I was just done," he told BuzzFeed.

Sabadini was upset after Trump insinuated the shooting could have been prevented if people had kept reporting Cruz.

So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior. Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again!
